The LIGO Open Science Center

我们建议开始LIGO开放科学中心（LOSC）的发展，该中心将向广泛的用户社区提供LIGO数据。 LOSC将收集LIGO实验室和LIGO科学合作组织（LSC）及其合作伙伴科学合作产生的相关数据产品，并将这些数据产品提供给外部用户沿着提供工具和支持，以实现这些用户的目标。LOSC将在高级LIGO观测运行之前、期间和之后运行，提供没有资金或以任何其他方式提供的用户服务。 由LIGO实验室和LSC提供的数据产品将包括低延迟瞬态GW事件候选广播;关于确认的瞬态和长期检测信息的目录; 6个月间隔的完整应变时间序列数据流以及相关的数据质量信息;以及与所有LIGO和LSC出版物相关的数字数据产品。 建成后，LOSC将提供（a）一个门户网站、客户工具和一层数据访问服务，用户可以通过这些服务发现和访问一系列LIGO数据和元数据产品;（B）长期数据管理;（c）用户文档、服务台、在线教程和用户反馈论坛;（d）赞助辅导、讲习班和会议，帮助用户从数据中获得最大的科学知识，并相互交流经验和研究结果，并向学习和科学委员会交流;以及（e）以LIGO数据为中心的资源，以促进LIGO和LSC关于引力波和相关科学的教育和公众宣传工作。在2013财年，我们将开始LOSC的初始开发阶段，并为先进LIGO运营时代（2014财年及以后）的持续开发和部署奠定基础。 LOSC公开发布LIGO数据将使人们能够广泛参与引力波物理学和天体物理学的进步。 数值相对主义者、相对论理论家、天文学家和天体物理学家将利用LIGO观测来更好地理解强弯曲时空的动力学，以及引力波源的起源和性质。LOSC将使整个相对论和天体物理学界的跨学科科学，使科学家能够提出更深层次的问题，并将该领域推向新的方向。它将与NASA和NSF虚拟天文台的其他天文数据系统互操作，以实现联合数据挖掘和与其他档案的交叉引用。它将通过与法国、印度、意大利和日本的引力波项目的互动，促进开放数据的国际努力。 它将通过在遥远的未来提供数据来扩展和利用LIGO观测。它将使LIGO数据能够用于全国和全世界的大学本科生和研究生以及业余和专业科学家的教育。 通过LIGO实验室的活动和LSC的外联工作，它将为公众外联提供资源，以培养年轻科学家和公众对引力波和多信使天文学的兴趣和兴奋。

We propose to begin the development of the LIGO Open Science Center (LOSC), which will give access to LIGO data to a broad user community. The LOSC will gather relevant data products generated by the LIGO Laboratory and the LIGO Scientific Collaboration (LSC) and its partner scientific collaborations, and make those data products available to outside users along with tools and support for those users' goals. The LOSC will operate before, during, and beyond operation of the Advanced LIGO observations, providing user services that are not funded or available in any other way. Data products, supplied by LIGO Laboratory and the LSC, will include low-latency transient GW event candidate broadcasts; catalogs with information about confirmed transient and long-duration detections; the full strain time series data stream in 6 month intervals with associated data quality information; and digital data products associated with all LIGO and LSC publications. When completed, the LOSC will provide (a) a web portal, client tools, and a layer of data access services through which the user can discover and access a range of LIGO data and metadata products; (b) long-term data curation; (c) user documentation, helpdesk, online tutorials, and user feedback forums; (d) sponsorship of tutorials, workshops and conferences to help users derive maximal science from the data and communicate their experiences and findings to each other and to the LSC; and (e) LIGO data-centric resources to facilitate LIGO and LSC education and public outreach efforts about gravitational wave and related science. In FY13 we will begin the initial development phase of the LOSC and provide a foundation for continued development and deployment in the era of Advanced LIGO operations (FY14 and beyond). The public release of LIGO data by the LOSC will enable broad participation in the advancement of gravitational wave physics and astrophysics. Numerical relativists, relativity theorists, and astronomers and astrophysicists will use LIGO observations to better understand the dynamics of strongly curved spacetime, and the origins and properties of gravitational wave sources. The LOSC will enable cross-disciplinary science throughout the relativity and astrophysics community, enabling scientists to ask deeper questions and carry the field in new directions. It will be interoperable with other astronomy data systems from both NASA and the NSF Virtual Observatory, to enable joint data mining and cross-referencing with other archives. It will promote international efforts for open data through interactions with gravitational wave projects in France, India, Italy, and Japan. It will extend and leverage the LIGO observations by making data available and usable into the far future. It will enable the use of LIGO data for education of university undergraduates and graduate students, and amateur and professional scientists, throughout the nation and the world. Through the activities of LIGO Laboratory and LSC outreach efforts, it will provide resources for public outreach to build interest and excitement in gravitational wave and multi-messenger astronomy in young scientists and the public.
